The Grand Festival (Japanese: グランドフェスティバル Grand Festival) is the anime-exclusive final challenge for all Pokémon Coordinators. The tournament is held once a year in several regions and is the Pokémon Contests' analog to the Pokémon League Conference.
The general structure of each Grand Festival is similar: Pokémon Coordinators must win at least five Contest Ribbons of a specific region in order to be able to participate in that region's Grand Festival. The winner receives the Ribbon Cup, as well as the title of Top Coordinator.
Due to the large number of participants, Grand Festivals has more judges in attendance.
The Hoenn Grand Festival is held in Slateport City, while the Kanto Grand Festival is held at Indigo Plateau. The Sinnoh Grand Festival is held at Lake Valor, which is also where the most recent Wallace Cup was held. There is also a Grand Festival for the Johto region, though it is unknown where it is held.
The tournament is divided into two parts: the appeals portion and the battle portion.
In the appeals portion, Coordinators show off their Pokémon's moves in order to impress the judges and the audience. The appeals are awarded points by the competition jury, and the Coordinators with the highest scores proceed to the next round.
In the appeals stage of Kanto and Hoenn Grand Festivals, there are two rounds to appeal. In the first, Coordinators have their Pokémon performing with no more than one move, while in the second, Coordinators have their Pokémon using as many moves as necessary. Contrasting this, the Sinnoh Grand Festival only has one appeals round instead of two. The competition is held under the Double Performance rule, which means that Coordinators must use two Pokémon in all rounds.
In all Grand Festivals, only the best 32 Coordinators proceed to the battle portion.
In the battle portion, Coordinators shows how skilled they and their Pokémon are when put into battle. All battles follow the Double Battle style. Competing Coordinators are matched-up randomly by computer up to the semifinals, which is the last round that computer will choose a random match-up. Whoever loses is out of the tournament. The Coordinator who wins the fifth and final round of this portion is then declared the winner of the entire competition.
A Top Coordinator (Japanese: トップコーディネーター Top Coordinator) is the highest known level of rank for a Pokémon Coordinator. The title is bestowed upon Coordinators who have won a Grand Festival. The following is a list of individuals who are Top Coordinators:
